An inflation device includes a balloon and a shaft coupled to one another via an overmold that includes a shut-off ridge. The shaft is in pressure communication with the balloon. Therefore, when fluid pressure is increased in the shaft the balloon may inflate. The use of shut-offs to form the overmold including shaping the shut-off ridge should result in an overmold with no flash and few or no bubbles within its structure.

Inflatable medical devices and methods for making and using the same are disclosed. The devices can be medical invasive balloons, such as those used for transcutaneous heart valve implantation, such as balloons used for transcatheter aortic-valve implantation. The balloons can have high strength, fiber-reinforced walls.

Providing a method for producing a balloon catheter, that is capable of uniformly heating and cooling the entire mold and less likely to cause temperature unevenness. A method for producing a balloon catheter which comprises a shaft extending in a longitudinal direction and a medical resin balloon provided at a distal end portion of the shaft, comprising the steps of inserting a resin tubular body (10) into a mold (20), and placing the mold (20) inside a thermal jacket (30) wherein a porous metal body (50) is disposed outside the mold (20) and inside the thermal jacket (30).

A serration balloon can have a number of different components and can be made in a number of different manners. One or more longitudinally extending members with periodic raised wedges can be attached to a medical balloon. They can be attached with a fiber coating, a polymer coating, or other methods. A polymer matrix can be used to bond the longitudinally extending member to the surface of the balloon. The fiber coating can be, for example, a thread or mesh that secures the longitudinally extending member to the balloon. The medical balloon can be an angioplasty balloon, such as an off-the-shelf angioplasty balloon.

A method of manufacturing includes forming a medical balloon with a scoring element along at least a barrel section by expanding a tubular parison in a mold cavity including a closed end groove corresponding to the scoring element. The scoring element may extend longitudinally, circumferentially, or helically, and a plurality of scoring elements may be provided. Medical balloons formed using the method and a mold for forming such balloons are also disclosed.

To provide a new balloon catheter enabling formation of, with high dimensional accuracy and excellent shape adaptability with respect to a balloon, an additional structure such as a blade and a reinforcement member to be additionally provided to the balloon. In this balloon catheter 10 provided with an expandable/contractible balloon 14 on the distal end side of a catheter 12, an additional structure 36 having a prescribed pattern is formed through electroforming or the like directly onto an inner circumferential surface 34 and/or an outer circumferential surface 82 of the balloon 14.

The present disclosure provides a balloon dilation catheter that includes a handle (102), a substantially rigid inner guide member (108) coupled to the handle, a shaft (118) arranged over the inner guide member, a balloon (120) coupled to the inner guide member, and a polymer ball tip (122) positioned at a distal end of the balloon. To treat a sinus drainage pathway of a subject using the balloon dilation catheter, the substantially rigid inner guide member is positioned into the drainage pathway of the sinus of the subject via a nasal passageway. The balloon is then inflated to expand or otherwise remodel the drainage pathway.

A method of forming a balloon for a medical device is provided including extruding a cylindrical tube of silicone material, partially curing the cylindrical tube, inflating the cylindrical tube, and fully curing the balloon. The cylindrical tube is partially cured by exposing the cylindrical tube to a first ultraviolet light source. The cylindrical tube is inflated within a mold to form the balloon. The balloon is fully cured by exposing the balloon to a second ultraviolet light source.

An inductively heated mold system enables rapid heating of the mold and rapid cooling to reduce thermal cycling times by employing an inductive coil in a heater module that inductively heats a ferromagnetic layer configured on the mold body, such as around the outside perimeter of the mold body. A cooling channel may be configured between the inductive coil and the ferromagnetic layer on the mold body to allow a fluid to be passed between the mold body and the heater module to rapidly cool the mold body for removal of the molded part. A plurality of heater modules may be employed that can be coupled together such that the cooling fluid passes through the coupled cooling channels from one module to a second module. In this way heater modules can be combined to provide an inductively heated mold system for a variety of mold body sizes, or lengths.

An embolic filter balloon is disclosed. The embolic filter balloon may comprise an inflatable balloon portion. Further, the inflatable balloon portion may be coupled to a filter member. The embolic filter balloon may be disposed in a body lumen. In some embodiments, the embolic filter balloon may be configured such that when the inflatable balloon portion is at least partially inflated the filter member extends at least partially across the body lumen. Such a configuration may allow the embolic filter balloon, when deployed, to filter particles greater than a predetermined size from a fluid in the body lumen.
